+Accept account deletion notifications
+=====================================
+
+Since September 2021, **eBay requires supporting customer account deletion/closure notifications**.
+As such, when eBay receives an account request for deletion, all eBay partners must confirm the
+reception of the request and take further action if necessary.
+
+Odoo has a notification endpoint to receive those notifications, confirm the reception of the
+request, and handle the first set of actions to anonymize the account details in **Contacts** and
+remove the customer's access to the portal.
+
+.. important::
+   Make sure to correctly :ref:`set up your subscription to the marketplace account deletion
+   notifications <ebay/subscribe-account-deletion-notifications>` as eBay may temporarily disable
+   the related eBay account until the subscription is completed.

+To subscribe to deletion/closure notifications, eBay needs a few details:
+
+- An **email address** to send notifications to if the endpoint is unreachable.
+- The **endpoint details**:
+
+  - The URL to Odoo's account deletion notification endpoint
+  - A verification token

+Verify the connectivity with the endpoint
+-----------------------------------------

+After setting the retrieved endpoint details in eBay's dashboard, consider testing the connectivity
+with the **Send Test Notification** button.
